GATE FOR ASH HOPPERS.

Application filed April 30, 1924. Serial No. 710,195.

To all whom t may concern.'

Be it known that we, ROBERT H. BEAU- MONT and HARVEY MARETTE, citizens of the United States, residing, respectively, in Philadelphia, Philadelphia` County, Pennsylvania, and East Orange, Essex County, New Jersey, have invented certain inprovements in Gates for Ash Hoppers, of which the following is a specification.

One object of our invention is to provide ine-ans for carrying 0E the water used in quenching hot ashes in an ash hopper.

A further object ot the invention is to provide a scraper, which removes the sludge troni the gate as the gate is opened, the sludge passing into the wagon, or car, being loaded with ashes.

In the accompanying drawings: n

Fig. 1 is a side view showing the ash hopper and the gate in section and illustrating our invention; Fig. 2 is a sectional view on the line 2-2,Fig. 1; Fig. 3 is a sectional plan view on the line 3 3, Fig. 2; illustrating the construction of the gate; and Fig. l is a detached, perspective view of the scraper.

Referring to the drawings, 1 is an ash hopper ot the ordinary type. 2 is the base ring of the hopper. 3 is the lire brick lining. Depending from the base ring, in the present instance, are hangers 4 to which the rails 5 are attached. These rails niay be attached to an overhead structure, independently of the hopper, it desired. 6 is a gate arranged to close the bottoni ot the hopper. The bottoni 7 ot the gate is solid and. is inclined from the point ai to the point je/ and is provided with a raised lip 7n. Mounted in the upper portion of the gate is a series ot longitudinally arranged grate bars 8. These grate bars are triangular. but they may be shaped differently without departing i'roin the essential features of the invention. The grate bars are placed a sutlicient distance apart to prevent the passage of the coarse ashes, but will allow the water used in quenching the ashes to pass into the hopper and with it a certain amount ot' line ashes or sludge. Alter passing between the grate bars, the water flows over the inclined bottom of the gate, discharging at the end p/ of the gate into a fixed trough 9, which is suspended from the ash hopper 1 hy straps 10, the sludge being retained by the lip 7a. y

11 designates an outlet pipe that connnunicates with the gutter, leading the water to any convenient discharge point. The gate is provided with flanged wheels 12, which travel on the rails 5. Motion is imparted to the gate hy fluid under pressure in a cylinder 13, in which is a piston llt. This piston has a rod 15, which is attached to a bracket 16 in the gate, Fig. 1.

17 designates a scraper, which is located under the grate hars and is arranged to rest on the bottoni 7 of the gate. The scraper has arins 18, which are pivoted at 19, to each side of the ash hopper, as shown clearlyin Figs. 1 and 2.

It will be noticed in Fig. 1 that the scraper is set at an angle so that, when the gate is opened, `it will accommodate itself to the inclined bottoni and will reinove any sludge that happens to pass between the spaces of the grate bars. When the gate nioves away troni the gutter-9, the sludge is deposited, with the ashes, in the wagon, or

car.

It will be seen hy the above invention that, when the ash hopper is loaded with ashes and is quenched with water, the water gradually seeps through the ashes and. passes through the space between the grate bars. As the bottoni ot the gate is inclined, the water flows into the Fixed gutter at the 'front of the gate.

When the gate is opened to discharge ashes from the hopper into a wagon, or car, the sludge that has been carried by the water past the grate bars and into the gate is removed 'troni the gate by the lined scraper and is discharged into the wagon, or car, with the ashes The grate bars are preferably arranged longitudinally of the gate so that they will slide niore readily under the ashes when the gate is opened. Other types ot grate hars may be used without departing troni the spirit of the invention, and, in place of the bars, a perforated plate, spaced bricks or other foraminous supports may be used to retain the ashes within the hopper and allow the quenching water to pass into the gate.

We claim:

l. The combination of an ash hopper; a gate arranged to be located under the hopper; `means'tor moving the gate into and out of position; a series of gratebars on the gate; and a fixed gutter at the front ot the gate; said gate being open at the front end to allow the water that is used inquenching the ashes to pass from the gate into the gutter. Y

2. The combinationot an ash hopper open at the bottom; a gate arranged to close the bottom `ot the hopper, said Vgate having an inclined bottom, the gate being open atone end; and a series of grate bars-at the `upper portion of the gate, said bars being spaced a suiiicient distance yapart to allow the water used in quenchingthe ashes to pass into the gate and `to iiow tothe open end thereof.

f3. The combinatio-n of an ashhopper open atthe bottom; a gate arranged to close the bottom of said hopper, said gate having a solid bottom; agrate in the `upper portion `ot' the gate; and a scraper arranged to -remove any sludge that has,l passed the grate when the gate is o-pened.

4:. The combination of an ash hopper open at the bott-om; a gate for closing the ash hopper, said gate having afsolid, inclined bottom; `a series-of grate bars in the upper portion of the gate spaced apart to allow the water that is used in quenching the ashes to pass into the body of the gate, said. water carrying with it a certain amount of sludge that accumulates in the bottom of the gate;

and a scraperpivotally mounted on the hopper and arranged to remove the sludge from the gate when the gate is opened.

5. The combination of an ash hopper open at the bottom; a fixed gutter at one end of the hopper; rails under the hopper; a gate arranged to travel on the rails; means for moving the gate into the closed or the open position, the gate having a solid bottom; inclined towards the ylixed gutter; a series of longitudinally arranged grate bars mounted on the gate, the gate being open at one end so that the water that passes between the bars will flow into the gutter; and means for removing sludge that accumulates on the bottom of the gate when vthe gate is opened.

6. The combination of'a hopper open `at the bottom; a gate arranged to move into and out of position in respect to the bottom ot' the hopper, saidfgate having a solid bottom; and a series ot grate bars spaced apart and arranged parallel to the line of movement of the gate, saidgate having an `outlet for the escape of water passing through the space between the grate bars.

7. The combination of an ash hopper; a gate arranged to be located under the hopper, said gate having asolid bottom provided with a lip at itsouter end to retain sludge; a grate in the upper portion ot the gate; and a scraper arranged to remove sludge from the bottom of the gate as the gate is opened.` l

8. The combination of an ash hopper open at the bottom; a. gate therefor; a toraminous support on thegate for the ashes an outlet for the escape of water passing through the oraniinous support; and means for moving the gate into and out of position.
